| 摘 要： | 为探究出胶囊型匀质物体下落时回弹高度的具体表达式，以及从概率分布的角度对前述的实际生活现象进行合理解释。对于匀质胶囊型物体旋转下落回弹的现象进行了简单理论建模，求解了物体的转动惯量，从动力学角度对此运动过程进行了理想情况下的理论分析，完整阐述了回弹高度高于初始高度的原因，并最终从概率分布的角度对回弹高度大于初始高度日常生活中这一现象的进行了解释。此外还通过Matlab理论建模进行模拟实验以及实际操作验证，最终得出了对于确定的一个胶囊型物体其下落回弹高度与转速和初始高度有关。 |

| Abstract： | This paper probes into the specific expression of the rebound height when the capsule type homogeneous object falls, and gives a reasonable explanation of the above-mentioned real life phenomenon from the perspective of probability distribution. A simple theoretical modeling was carried out for the phenomenon of the springback of the rotating fall of the homogeneous capsule object, and the moment of inertia of the object was analytically solved. The theoretical analysis of the motion process under ideal conditions is carried out from the perspective of dynamics, and the reason why the springback height is higher than the initial height is completely explained. Finally, from the perspective of probability distribution, the phenomenon that the rebound height is greater than the initial height in daily life is explained. In addition, with Matlab theoretical modeling simulation experiment and practical operation verification, we conclude that the fall rebound height of a capsule object is related to the speed and initial height. |
